Title: Doping metal oxide layers
IPC: C30B31/08
Filed: 1972-03-03
Abstract: 1374333 Doping oxide semi-conductors; image pick-up tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 March 1972 [6 March 1971] 9997/72 Headings H1K and H1D The invention concerns a process for doping the surface of a porous layer of lead monoxide, e.g. a target for a vidicon tube of which it is desired to adjust the spectral response, with an element which replaces oxygen in the lead monoxide by chemisorption of a reactive gas-containing the replacing element. The process comprises firstly adsorbing the reactive gas into the lead monoxide surface at a temperature below that at which the reactive gas decomposes and in a concentration less than that required to replace the oxygen atoms of all the surface molecules by the replacing element and then, in the absence of any further reactive gas, raising the temperature of the lead monoxide layer so that the adsorbed reactive gas decomposes releasing the replacing element, which then replaces the oxygen atoms of a proportion of the surface molecules, the replaced oxygen escaping as a gaseous compound. For vidicon tube target manufacture the lead monoxide layer is preferably polycrystalline with plateshaped crystallite aligned perpendicularly to the glass face plate of the tube which carries a tin oxide or indium oxide layer on which the lead monoxide is vapour deposited. Suitable reactive gases are hydrogen compounds of Cl, Br, I, F, S, Se or Te, and details of deposition and decomposition temperatures and of appropriate reactive gas concentrations are given for several specific embodiments. Reference is made to bombardment of the doped lead monoxide layer with oxygen ions. If it is desired to dope the lead monoxide surface with two oxygen-replacing elements; e.g. firstly Cl or Br and then S, Se or Te; it is not necessary to maintain the temperature of the layer so low during the adsorption process for the second dopant as would be the case if this dopant were used on its own. This enables Te to be used as a dopant, obtained from H 2 Te reactive gas, the temperature required when Te alone is used being so low that no appreciable vapour pressure occurs.

Filed: 1993-01-07
Abstract: PURPOSE:To input handwritten characters directly at a position where the characters are to be inputted (displayed) and generate a certain character string. CONSTITUTION:An insertion position determining process part 18 determines an indicated position as a character insertion position for a document displayed in a document window. A character frame display control part 26 sets and displays a character handwriting frame at the character insertion position. A character recognition part 22 performs character recognition based upon handwriting data inputted in the character handwriting frame and inputs the recognition result at the character insertion position. At this time, a document display control part 28 scrolls the document in the document window on the screen so that the character insertion position after the character input matches the character handwriting frame. Consequently, the character handwriting position is fixed and the character can be inputted directly at the character input position for the displayed document.

Title: Liquid fluid combustor
Inventor: YAMAMOTO KATSUHIKO
IPC: F23D11/34
Filed: 1978-01-09
Abstract: PURPOSE: For preventing generation of malodor, soot and CO upon combustion or fire extinguishment, to let secondary air flow into a guide tube through the secondary air hole provided on the guide tube portion in the vicinity of a burner portion.  
     CONSTITUTION: The liquid fuel in an atomizing tank 1 is atomized by applying vibration on an ultrasonic vibrator 2 from an oscillator 5. Thus-obtained atomized fuel particles are carried to a burner portion 10 through said guide tube 7 by the air fed from a blower 11. In the meanwhile, when said blower has started, secondary air flows to a burner portion 10 through the clearance betweeen an outer tube 8 and said guide tube 7. Next, said secondary air flows into said guide tube 7 through a secondary air hole 7a and is mixed with said atomized fuel particles therein. Namely, since said secondary air is mixed just before said atomized fuel particles are combusted in said burner portion 10, good mixation and complete combustion are performed. Further, since the vicinity of said burner portion 10 is cooled down by said secondary air, said liquid fuel having attached to said burner 10 is prevented from becoming uncombusted gas upon fire extingishment.

Filed: 1990-01-08
Abstract: PURPOSE:To manufacture the hearth roll for a heat treating furnace for steels in which the generation of wrinkles and cracks is suppressed by joining the inner circumferential face of a shell constituted of a heat-resistant steel with a heat transfer layer constituted of a high heat conducting metal via a brazing filler metal layer in a laminated manner. CONSTITUTION:A brazing filler metal layer (e.g., of Ni) is thermal-sprayed and formed on the outer circumferential face of a hollow cylindrical body constituted of a high heat conducting metal to form a heat transfer layer 3 (e.g., constituted of Cu and having about 15 to 30 mm thickness).
